Micropiles socketed in rock are used in the Chicago area for rehabilitation work for infrastructure systems. They differ from many micropiles in that they are designed based on end-bearing rather than interface shear. There are no specially-created procedures for designing micropiles socketed in rock. Their axial capacities typically are determined either on the basis of provisions in building codes not specifically related to micropiles or conventional design methods for drilled shafts. The capacity of a micropile socketed in rock is selected as either a conservative estimate of structural capacity or its end bearing capacity neglecting the shearing resistance along its side. Results of a number of field axial load tests indicate the load deflection responses are essentially linear to code-specific design loads, suggesting the true capacity of the piles are significantly higher than currently-allowed values.
